Do you have the WeatherLink 2.0 app? I noticed the original was crashing for the last week or so when you tried to add a station and sometime during the last couple days it quit displaying data for the stations already loaded.
I'm surprised that the 1.0 app is working at all. It looks like the migration to 2.0 is essentially complete with just 137 stations (out of around 28,000 total) still showing on the 1.0 map, of which 87 seem to be in Finland, though not all actively updating (Hello Ilkka, if you visit here at all - what's that all about then?). Otherwise the world map is essentially blank other than a residual 50 or so in the US.
So I think we can conclude that the migration to 2.0 is pretty much done and that 1.0 may be turned off completely before too long. So may as well delete the 1.0 smartphone app.
